First, sound does not work anymore. I get this log (/var/log/syslog) :

I don't know enough about the sound card modules to be able to
suggest
anything very useful, sorry :(. All that I CAN tell you is that no alsa
modules are loaded on my machine and sound works perfectly, though
I'm running
Kubuntu 10.04 which doesn't use Pulseaudio by default... very early on I
enabled the use of pulse. So maybe this is something to do with the
Pulseaudio
config and maybe deprecated ( for Ubuntu ) kernel modules rather than
real
hardware issues. Maybe if you could find the sound related modules
that aren't
loaded in 2.6.37 that were in 2.6.36 and I can see if they have just
been
removed from the default build?
I'm running Archlinux on a Z1390S.
I took Adam's 2.6.37 kernel patch and kernel config, and built myself two
versions of the 2.6.37 kernel:
1. stock 2.6.37-rc1 from kernel.org
2. the "Ubuntu" kernel obtained by 'git clone
git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git'
In both cases I was able to apply the patch and get a working kernel
that is
ableto resume from sleep, using Intel card. However, my sound also
does not
work. I'm not using pulseaudio, just basic ALSA stuff; udev loads
snd_hda_intel, etc. Audio works fine for me with Archlinux's 2.6.35
kernel,
as well as when I was using Adam's 2.6.36 kernel on an Ubuntu install.
Sooo, for what it's worth, here's another vote of "sound does not work on
2.6.37". I'll try using 'make menuconfig' to pore through the options
and
see if I notice anything that could be affecting it.
I think I solved the sound problem. A nice howto is here:
https://help.ubuntu.com/community/HdaIntelSoundHowto
The sound chipset on the Z1390 is an ALC889.
All you have to do to get sound is change the model option of the
snd_hda_intel driver:
In the file /etc/modprobe.d/alsa-base.conf add the line:
options snd-hda-intel model=sony-vaio-tt
(the often suggested model=sony-assamd is for the ALC262 chipset)
The "sony-vaio-tt" model works, but the laptop microphone is still not
working. Many more models are listed in the file
/usr/share/doc/alsa-base/driver/HD-Audio-Models.txt.gz , under
ACL882/.../889. Maybe another one will make the microphone work?
